Yes that is pretty much how fans work. Though with an additional 5 fans, if you are intending to use up all the "optional" fan positions, you may well have to also get a fanbus of some sort, unless your mobo has like 8 fan headers, or do some cable splicing. But I would also be asking myself, do I really need 7 case fans going?
 
Expensive fans mate, especially for case fans.

Static pressure doesn't matter very much, I'd probably go with the Slipstream instead, or with Gentle Typhoon if noise matters more than airflow to you.

Most aftermarket ones come with 3 pin connectors, some will have 4 pin molex connectors. The 4 pin ones you plug into the power supply and tolerate the noise, or change to 7V by moving a couple of pins around on the molex plug. The 3 pin ones connect to your motherboard, or to a fan controller. I'm fond of the Y splitters which allow two 3 pin fans to be plugged into one motherboard header, without them I would have had to get a fan controller of some sort.

You can splice the cables with much the same effect, I may do this myself in the near future.

A while ago I went with the same approach of putting a powerful fan everywhere it would fit. This was not a brilliantly researched decision, and I now have several of the S-flex sitting in a box. None are used as case fans anymore, though they did work perfectly well as such. Sometimes less is more with fans, you may well find you get lower temperatures by blocking off the side vents than by putting fans there.
 
cheers.they just looked empty. i wondered it there was anything else i had to buy. ilo have a look at a fan bus. i probavbly wont need them but they cant hurt can they? and 8 running at 10% would be quieter than at 20% right?
 
At 10% voltage not one of your fans would spin, but I see your point. You can choose between 12, 7 and 5V quite easily without a fanbus, where almost all work at 7 with little noise and an appreciable fraction cant start at 5.

The question of do two fans moving the same air volume make less noise than one is a difficult question, and depends a bit on set up. It's a sticky over here Click

Spending 60 quid on fans for a 50 quid case seems strange to me.
 
If you worried about noise. get 5 of the noctua 800rpm or 5x the scythe 500rpm. You won't need a controller and you just plug them into the psu. No point letting the mobo control them.
 
cheesr guys. i didnt meen power i meant speed (although that may equate to power) but yeah. i guess i dont need them verry fast with that many. and i will probably buy them in instalments as and when i get the money.
